This is a fairly common requirement when importing text files in to a
word-processor. Search and replace is the usual tool and lots of people
have written macros to do this. First replace sequential newlines with a
nonsense string: I use :ZZ: because that's what my first sysadmin used.
Then replace all remaining newlines with a space. Lastly replace the
nonsense string with a newline. Job done.
